中文摘要:
      采用碱熔再酸化分解样品,电感耦合等离子体原子发射光谱法(ICP—AES)测定高铁土壤中Al。通过逐级扩大线性范围的方式,选取测定高含量Al的合适谱线;在标准中逐级加入铁基体,考察了铁基体浓度从20μg/mL到80μg/mL时对测定Al的各谱线的干扰情况。用ICP—AES对国家标准物质GSS-1,GSS-2,GSS-3,GSS-4,GSS-5进行测定,测定值与认定值的相对误差(RE)在-0.37 %~0.31%之间,RSD(n= 5)为0.26%~0.75% 。
英文摘要:
      Al in high-speed rail soil was determined by ICP-AES using alkali melting and acidification decomposition samples. By expanding the linear range step by step, the suitable spectral line for determining high content Al was selected. The interference of the iron matrix concentration from 20 μg / mL to 80 μg / mL on the spectral lines of Al was investigated by adding the iron matrix step by step in the standard. The national standard substances GSS-1, GSS-2, GSS-3, GSS-4, GSS-5 were measured with ICP-AES, and the relative error(RE) between the measured value and the determined value was -0.37 % to 0.31 %. RSD(N = 5) is 0.26 % ~ 0.75%.
